Seventy two genotypes of sainfoin (Onobrychis viciifolia Scop) were sown using lattice design under irrigation condition in Alborz, station Karaj, Iran during 2009–10. Forage dry matter (DM) yield, leaf to stem ratio, growth condition, stem density, plant height, flowering time and resistance to sainfoin powder mildew were studied over 2 years. The analysis of variance showed significant differences for all traits (P<O.01). The correlation coefficient between DM yield and growth condition, plant height and stem density was positive and significant. Resistance to disease had negative significant relationship with late-growing, plant height, stem density and forage yield. In addition, Ward cluster analysis was done and divided into 4 genotype groups. In coordinate axis, 1st and 2nd factors demonstrated a good agreement between cluster and factor analysis.
